You invest your time and effort breaking up that monolithic Frankenstein into a suite of elegant composable micro-services, you containerize them and you deploy them somewhere in the cloud. Then you proudly watch it all come together reaping the benefits of the most scalable architectures. It is all fine and dandy from this point on. Too good to be true? Of course! This session is about what to do when you wake up to find yourself in the weeds diagnosing that first bug and tracing calls through the convoluted web of micro-services of your own doing. Through a series of demos and code snippets, we will introduce the most important open-source projects tools to strike the right balance of monitoring at the infrastructure, container, and services.
